Find out how the TSF at Benambra Mine was rehabilitated

The Benambra Mine only operated for four years, but in that time produced an enormous amount of tailings, approximately 700,000 tonnes. But when the mine was abandoned during a company liquidation, it was left to the state government to secure the TSF and the toxic materials it held.

As part of a massive rehabilitation program in 2006, the site incorporated a strict monitoring system. This system has revealed significant progress in the site’s restoration. That includes stabilized, near-neutral water, a massive 90% decrease in dissolved metal concentrations, and a reduction in sulphate concentration from 2,000 mg/L in 2006 to 50 mg/L in 2013.

Ongoing monitoring has also found that downstream seepage from the TSF in nearly neutral, and water quality of the downstream wetland environment is vastly improved.
